Description

Technical Field

[0001] This utility model relates to the technical field of annular furnaces for steel ball forging, and in particular to an annular furnace for steel ball forging. Background Technology

[0002] Steel balls are classified into ground steel balls, forged steel balls, and cast steel balls according to their production and processing technology. Forged steel balls are produced using a ring furnace.

[0003] In the prior art, utility model patent CN213944759U discloses a ring furnace for steel ball forging, including a furnace body. A heat dissipation box is fixedly installed at the bottom of the inner wall of the furnace body, and a condenser is fixedly installed at the bottom of the inner wall of the heat dissipation box. A heat dissipation pipe is fixedly inserted on the outer surface of the heat dissipation box, and a water pump is fixedly installed at the top of the heat dissipation box. The output end of the water pump is fixedly connected to a pressure boosting pipe. A heat dissipation plate is fixedly welded between the two sides of the inner wall of the furnace body, and a heat-conducting copper pipe is fixedly inserted on the outer surface of the heat dissipation plate. A heat-conducting block is fixedly connected to the end of the heat-conducting copper pipe away from the heat dissipation plate. This utility model adds a rapid cooling structure for splashed molten slag, avoiding the hot material from scalding the inner wall of the furnace body, extending the service life of the device, and avoiding resource waste. It also adds a molten slag scraping structure, avoiding the problem of difficult cleaning due to large accumulation, and extending the service life of the anti-splashing device.

[0004] In the aforementioned patented technology, the ring furnace for forging steel balls scrapes the slag from the top of the heat sink plate through a scraping structure. However, during the scraping process, the push rod is pushed inward by the cooperation of the protrusion and the roller, which compresses the spring and causes the push rod to push the scraper outward. Then, under the action of the spring rebound, the push rod drives the scraper to return to its original position. Over time, the spring will fatigue and the rebound will be insufficient to return the push rod and scraper to their original positions. If the push rod cannot return to its original position, the protrusion and the roller cannot maintain contact, and the scraper cannot be pushed properly to scrape, thus affecting the slag removal effect and making it impractical. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a ring furnace for steel ball forging that can ensure scraper reset, keep the scraper moving normally, ensure good scraping effect on molten slag, and improve practicality.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ring furnace for steel ball forging, comprising a furnace body and a scraping mechanism. A heat dissipation plate is fixedly welded between the two sides of the inner wall of the furnace body. A cleaning hole is provided at the left end of the furnace body, and a slag outlet is provided at the right end. The scraping mechanism includes a fixing plate, which is fixedly connected to the inner wall of the cleaning hole. An internal threaded sleeve is rotatably mounted on the middle of the fixing plate via a bearing. A worm gear is fixedly mounted on the outer left wall of the internal threaded sleeve. A transmission screw is screwed onto the internal threaded sleeve. Two sets of support plates are symmetrically fixedly connected to the left end of the furnace body. A motor is fixedly mounted on the rear support plate. A transmission worm is fixedly connected to the output end of the motor. The transmission worm is rotatably mounted on the two sets of support plates and meshes with the worm gear. A connecting seat is fixedly connected to the right end of the transmission screw. The connecting seat is located inside the furnace body, and a scraper is mounted on the connecting seat for scraping the molten slag from the top of the heat dissipation plate.

[0008] Preferably, the scraper is integrally fixed with a docking block at the left end, the docking block has a positioning screw hole at the top, the connecting seat has a docking groove at the right end that cooperates with the docking block, the connecting seat has a threaded hole at the top end that communicates with the docking groove, a fixing bolt is screwed into the threaded hole, and the docking block is inserted into the docking groove through the cooperation of the fixing bolt and the positioning screw hole.

[0009] Preferably, a baffle is fixedly connected to the left end of the furnace body, and the baffle covers the worm gear and the transmission worm.

[0010] Preferably, a limiting platform is fixedly connected to the left end of the transmission screw.

[0011] Preferably, a reinforcing plate is fixedly connected between the bottom end of both sets of support plates and the left end of the furnace body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, initially the scraper is positioned on the left side of the heat sink plate, with its bottom end in contact with the top of the heat sink plate. After the molten slag at the top of the heat sink plate cools, the scraping of the molten slag at the top of the heat sink plate begins. By starting the motor, the transmission worm gear is driven to rotate, causing the transmission worm gear to drive the internal threaded sleeve to rotate clockwise through the worm wheel. This causes the internal threaded sleeve to drive the transmission screw to move to the right, and the transmission screw to push the scraper to the right through the connecting seat. Thus, the scraper pushes the molten slag at the top of the heat sink plate out through the slag outlet. Immediately afterwards, the motor drives the transmission worm gear to rotate in the opposite direction, causing the transmission worm gear to drive the internal threaded sleeve to rotate counterclockwise through the worm wheel. This causes the internal threaded sleeve to drive the transmission screw to move to the left, and the transmission screw to drive the scraper to move to the left through the connecting seat. This allows the scraper to return to the left side of the heat sink plate, thus ensuring the scraper resets and moves normally, guaranteeing a good scraping effect on the molten slag and improving practicality.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] Example

[0021] Please see Figures 1-5This utility model discloses a ring furnace for forging steel balls, comprising a furnace body 1 and a fixed plate 3. A heat dissipation plate 2 is fixedly welded between the two sides of the inner wall of the furnace body 1. A cleaning hole is provided at the left end of the furnace body 1, and a slag outlet is provided at the right end. The fixed plate 3 is fixedly connected to the inner wall of the cleaning hole. An internal threaded sleeve 4 is rotatably mounted on the middle of the fixed plate 3 via a bearing. A worm gear 5 is fixedly mounted on the outer left side of the internal threaded sleeve 4. A transmission screw 6 is screwed onto the internal threaded sleeve 4. Two sets of support plates 7 are symmetrically fixedly connected to the left end of the furnace body 1. A motor 8 is fixedly mounted on the rear support plate 7. A transmission worm 9 is fixedly connected to the output end of the motor 8. The transmission worm 9 is rotatably mounted on the two sets of support plates 7 and meshes with the worm gear 5. A connecting seat 10 is fixedly connected to the right end of the transmission screw 6. The connecting seat 10 is located inside the furnace body 1, and a scraper 11 is mounted on the connecting seat 10 for scraping off the slag at the top of the heat dissipation plate 2. In use, initially the scraper 11 is positioned on the heat dissipation plate 2. On the left side, the bottom end of scraper 11 contacts the top end of heat sink 2. After the slag at the top of heat sink 2 cools, scraping begins. The motor 8 drives the transmission worm 9 to rotate, which in turn drives the internal threaded sleeve 4 to rotate clockwise via the worm wheel 5. This causes the internal threaded sleeve 4 to move the transmission screw 6 to the right, which in turn pushes the scraper 11 to the right via the connecting seat 10. The scraper 11 then pushes the slag at the top of heat sink 2 out through the slag outlet. Immediately afterwards, the motor 8 drives the transmission worm 9 to rotate in the opposite direction, which in turn drives the internal threaded sleeve 4 to rotate counterclockwise via the worm wheel 5. This causes the internal threaded sleeve 4 to move the transmission screw 6 to the left, which in turn drives the scraper 11 to the left via the connecting seat 10. This returns the scraper 11 to the left side of heat sink 2, ensuring its reset and normal movement, guaranteeing effective slag removal and improving practicality.

[0022] The scraper 11 is integrally fixed with a docking block 12 at its left end. The top of the docking block 12 is provided with a positioning screw hole. The right end of the connecting seat 10 is provided with a docking groove 13 that mates with the docking block 12. The top of the connecting seat 10 is provided with a threaded hole that communicates with the docking groove 13. A fixing bolt 14 is screwed into the threaded hole. The docking block 12 is inserted into the docking groove 13 by the engagement of the fixing bolt 14 and the positioning screw hole. The scraper 11 is installed by the docking block 12 and the docking groove 13 and fixed by the fixing bolt 14. This method allows the scraper 11 to be easily disassembled for replacement or cleaning, improving convenience.

[0023] A baffle 15 is fixedly connected to the left end of the furnace body 1. The baffle 15 covers the worm gear 5 and the transmission worm 9. By setting the baffle 15, it can cover the worm gear 5 and the transmission worm 9, preventing them from being affected by external interference during the transmission process and improving protection.

[0024] The left end of the transmission screw 6 is fixedly connected to a limiting platform 16. By setting the limiting platform 16, when the internal threaded sleeve 4 drives the transmission screw 6 to move to the right, the limiting platform 16 plays a role in limiting the transmission screw 6 and preventing the left end of the transmission screw 6 from coming off the internal threaded sleeve 4.

[0025] A reinforcing plate 17 is fixedly connected between the bottom end of the two sets of support plates 7 and the left end of the furnace body 1; by setting the reinforcing plate 17, the connection between the support plate 7 and the furnace body 1 can be made more firm and stable.

[0026] This utility model discloses a ring furnace for forging steel balls. Its working principle is as follows: Initially, the scraper 11 is positioned to the left of the heat dissipation plate 2, with its bottom end in contact with the top of the heat dissipation plate 2. After the slag at the top of the heat dissipation plate 2 cools, the slag is scraped off. The motor 8 drives the transmission worm gear 9 to rotate, causing the transmission worm gear 9 to drive the internal threaded sleeve 4 to rotate clockwise via the worm wheel 5. This, in turn, causes the internal threaded sleeve 4 to drive the transmission screw 6 to move to the right. The transmission screw 6, through the connecting seat 10, pushes the scraper 11 to the right, thus pushing the slag at the top of the heat dissipation plate 2 out through the slag outlet. Immediately afterwards, the motor 8 drives the transmission worm gear 9... Reverse rotation causes the transmission worm 9 to drive the internal threaded sleeve 4 to rotate counterclockwise via the worm wheel 5. This, in turn, causes the internal threaded sleeve 4 to drive the transmission screw 6 to move to the left. The transmission screw 6 then drives the scraper 11 to move to the left via the connecting seat 10, bringing the scraper 11 back to the left side of the heat sink 2. In this utility model, both the furnace body 1 and the heat sink 2 are referenced from a ring furnace for steel ball forging with patent publication number CN213944759U, which is already disclosed prior art. The other specific structural components and working principles have been described in detail in that published patent. Therefore, this application does not show all the remaining structures in the figures, and will not elaborate further here.
